Seems like there's a market for aluminum 5/8 speed handles. I don't see any reason one couldn't make them with a manual mill, granted milling that hex would be a PITA.
I have a CNC and am quite good with CAD/CAM, it wouldn't be much trouble to design something in CAD and process some g-code programs.
I'm wondering what a 6061 5/8 speed handles would sell for? I'm not set up for anodizing, but can definitely leave them in the white, or use molycoat/cerakote.
Without doing any math, i'd think an aluminum 5/8 socket not able to handle the torque being used for a vice handle.
Guys that have them, is this not an issue?
